There will be an annual advanced GPR workshop every winter starting December, 2024. I have hosted these workshops in 2020 and 2022, and so far have had 54 participants from every inhabitated continent in the world.
Those who complete the workshop will be accredited GPR practicioners and will be included in a list with contact information and on an interactive map of the USA, Europe and the rest of the world.
